Question

find the breadth of the rectangle whose length is 52 M 60 cm and perimeter is 140 m

Answer 1

Perimeter is the distance covered along the boundary of a closed figure.

Perimeter = Sum of the distances or lengths of all the sides

= PQ + QR + RS + SP.

= 3 cm + 2 cm + 1 cm + 4 cm.

= (3 + 2 + 1 + 4) cm

= 10 cm

The perimeter of the given figure is 10 cm.

Answer 2

Heya☺

Perimeter of rectangle = 2(l+b)

140 = 2(52 ×60/100 +b)

70 = 312/10 + b

b = 70 - 312/10

b =( 700-312) ÷10

b= 388÷10

b= 38.8 m
