Question

if diagonal of rectangle is 65 cm and one side is 39 cm find the others side​

Answer 1

Answer:

(1) Length of the rectangle is 5.2 cm.

Breadth of the rectangle is 2.5 cm.

Area of a rectangle = l × b

= 5.2 cm × 2.5 cm = 13 sq cm

∴ The area of the rectangle is 13 sq cm.

(2) Length of the rectangle is 2.1 m.

Breadth of the rectangle is 1.5 m.

Area of a rectangle = l × b

= 2.1 m × 1.5 m = 3.15 sq m

∴ The area of the rectangle is 3.15 sq m.

(3) Length of the rectangle is 3.5 m.

Breadth of the rectangle is 1.2 m.

Area of a rectangle = l × b

= 3.5 m × 1.2 m = 4.2 sq m

∴ The area of the rectangle is 4.2 sq m.
