Question

find the area of rhombuswhose diagonal are ( x+2) and (x-7) ​

Answer 1

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
