Question

Area of rhombus is 70cm whose diagonals are of length (x+2)cm,(x-2)cm find the length of the rhombus

Answer 1

Answer:

area of rhombus =1/2×product of diagnol

70cm=1/2 ×(x+2) ×(x-2)

70cm= 1/2 ×(2x-2x +2x-4)

70cm= 1/2×(0+ 2x-4)

70cm=1/2×(2x-4)

70cm=1×2x-2

70cm+2=2x

72cm=2x

72cm/2=x

36cm= x
