Question

the perimeter of a rectangle is 150 cm if its length is 50 cm then find the area of rectangle​

Answer 1

Answer:

Perimeter = 150 cm

Length ( l ) = 50 cm

Therefore,

Perimeter of a rectangle = 2( l+b)

150 = 2 ( 50 + b)

150 = 100 + 2b

150 - 100 = 2b

50 = 2b

b = 50 ÷ 2

b = 25 cm

Therefore,

Area of a rectangle = l × b

= 50 × 25

= 1250cm

Your answer is:

Area of the rectangle is 1250cm
