find the point which divides the linesegment joining the points( a+b,a-b)and (a-b,a+b) in the ratio 3:2 internally

Answer»

Step-by-step EXPLANATION:

Let the POINT A( a+b ,a-b) and B (a-b , a+b ) which divide the linesegment AB at O ( X, Y) in the ratio 3:2 internally .

FORMULA : [mx2+nx1/m+n , my2+ny1/m+n]

put the VALUE

[3a-3b + 2a+2b /5 , 3a+3b + 2a-2b / 5]

[5a-b /5 , 5a+b /5]

[5( a-(b÷5) ) /5 , 5( a+(b÷5) ) /5]

[a-b/5 , a+b/5]

Find the area of the quadrilateral ABCD.Here, AC=22 cm, BM-3 cm,18 cm and is a DN=3 cm, andBM perpendicular to AC, DN perpendicular to AC.

Answer»

Answer:

231

Step-by-step explanation:

Area of TRIANGLE DAC = 1/2 × 22 × 18= 198

Area of triangle ABC= 1/2 × 22 × 3 = 33

Area of the quadrilateral = Area of triangle DAC + Area of triangle ABC

= 198 + 33

= 231
