Question

He length of the diagonal of the rectangle
The diagonal of a rectangle is 25 cm and its length is 20 cm. Find the breath and perimeter of
the rectangle​

Answer 1

Diagonal of rectangle =25cm

Length of rectangle =20 cm

Breath of rectangle = √(diagonal)² −(length)²

= √25² −20²

= 15

Area = length× breath

= 15 × 20 cm²

= 300 cm²

Answer 2

Answer:

$d = 25 \\ l = 20 \\ b = {25}^{2} - {20 }^{2} \\ b = 625 - 400 \\ b = 225 \\ b = \sqrt{225} \\ b = 15 \\ p = 2 \times (l + b) \\ = 2 \times (20 + 15) \\ = 2 \times 35 \\ = 70$
