Question

The lengths of diagonals of a rectangle are (3x-5) cm and (x+7) cm. Find the lengths of the diagonals.

Answer 1

Answer:

We know that the diagonals of rectangle are equal.

Let (3x-5) cm be d₁ and (x+7) cm be d₂.

d₁=d₂

3x-5=x+7

Transpose the constants on right side and variables on left side

3x-x=7+5

2x=12

x=6.

d₁=3x-5=3×6-5=13cm.

since d₁=d₂, d₂=13cm.

THUS, THE DIAGONALS OF RECTANGLE IS 13cm.

HOPE THIS HELPS :D

Answer 2

Step-by-step explanation:

length of the diagonal is 13 cm
