Tapezium and a PolygonLISFind the height of the trapezium, the sum of the lengths of whose bases is 50 cm, and whose area is500 cm? |
|
Answer» Let height of trapezium be h Given,Sum of bases b = 50 cmArea of trapezium A = 500 cm^2 We know,Area of trapezium = 1/2*b*h500 = 1/2*50*hh = 500/25 = 20 Therefore, Height of trapezium = 20 cm |

14:The ratio of the length of the parallel sides of a trapezium is 4: 1. The distance between themis 10 cm. If the area of the trapezium is 500 cm”, find the lengths of the parallel sides. |
|
Answer» Let the sides be 4x and x Given h=10 cm A=500cm^2 Now, Area is given as 500 =1/2 × 10 × (4x+x) 500 =10 × 5x 50x = 500 x= 500 / 50 = 10 4x = 4 × 10 = 40 x = 10 = 10 the parallel sides are 40 cm and 10 cm. solve(14)-Given that. b:a=4:1let be, b=4x. and. a=x h=10cm. Area(A)=500cm^2formula of area of trapezium, A=(a+b)h/2500=(4x+x)10/2500=5x*5 after transfar 5*5500/5*5=x20=xb=4*x=4*20=80cma=x=20cm if any doubt then ask me 500 |

find the AP. (3,5,7,9,...20: How many three digit natural numbers are divisible by 77 (128)L tr. 11 Its 2ă¤th term rs three times Its 8th te21 |
|
Answer» The first three digit number which is divisible by 7 is 105 and last three digit number which is divisible by 7 is 994. This is an A.P. in which a = 105, d = 7 and l = 994. Let the number of terms be n . Then tn = 994. nth term of A.P tn = a + (n - 1)d. 994 = 105 + (n -1)7. 889 = 7(n-1) n -1 = 127 n = 128. Hence, There are 128 three digit numbers which are divisible by 7. |

3)How many three digit natural numbers are divisible by 4? |
|
Answer» From 1- 40 , 10 numbers divisible by 4 From 41–80,10 more numbers From81-100, 5 more numbers So between 1–100 ,25 numbers are divisible by 4. So three digits numbers comes in the range of 100 and 1000. Therefore the number of digits divisible by 4 will be 25*9 =225 225 +1=226 1 is added because 100 is also a three digit number divisible by 4. |
