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
