Find the area of rhombuswhose diagonal are ( x+2) and (x-7) |
|
Answer» Step-by-step EXPLANATION: Area of RHOMBUS = 1/2 ×d1×d2 Diagonals are given : (x+2 ) and (x-7) We can APPLY this formula for rhombus we know that there are 2 diagonal in a rhombus and it's of 1/2 So we can FIND it 1/2 × (x+2) ×(x-7) = ( x²-7x+2x-14 ) 2 = (x²-5x-14) / 2 = [ x²-(7-2)x-14] / 2 = (x²-7x+2x-14) / 2 = [X ( x-7) +2 (x-7) ] / 2 = [ (x-7) (x+2) ] / 2 Ans Hence the ANSWER is 2 |
