In a Trapezium , sum of two parallel sides is 30 cm and distance between them is 5 cm . Find its area.150 cm²100 cm²75 cm²50 cm² |
|
Answer» LET the lengths of the two parallel sides of the trapezium be X and 2 X cm respectively. We know that Area of the trapezium= 21 (SUM of parallel sides) × (DISTANCE between them) ∴180= 21 (x+2x)×12 or 180×2=3x×12 or 180×2=3x×12 or 36x=360 or x=10 ∴ The sides of the trapezium are 10 cm and 20 cm respectively. |

Answer» LET A be the first TERM and D the COMMON difference of A.P. T p =a=A+(p−1)D=(A−D)+pD (1) T q =b=A+(q−1)D=(A−D)+qD ..(2) T R =c=A+(r−1)D=(A−D)+rD ..(3) Here we have got two unknowns A and D which are to be eliminated. We multiply (1),(2) and (3) by q−r,r−p and p−q RESPECTIVELY and add: a(q−r)+b(r−p)+c(p−q) =(A−D)[q−r+r−p+p−q]+D[p(q−r)+q(r−p)+r(p−q)]=0. |

2) Multiplyi V5- V7) v2 |
|
Answer» Step-by-step explanation: GIVEN, A={1,2,3,4,5},B={2,4,6,8} and C={3,4,5,6} For the LHS: Union of two SETS will have the ELEMENTS of both sets. So, B∪C={2,3,4,5,6,8} A−(B∪C) will have elements of A which are not in (B∪C) So, A−(B∪C)={1} ..... (1) For the RHS: A−B will have elements of A which are not in B. So, A−B={1,3,5} A−C will have elements of A which are not in C. So, A−C={1,2} Intersection of two sets has the common elements of both the sets. ⇒(A−B)∩(A−C)={1} ..... (2) From (1) and (2), we have A−(B∪C)=(A−B)∩(A−C) Hence, the given expression is true. |
