Question

The perimeter of a rectangle are 230 cm if length of rectangle is 80. find breadth and area of rectangle​

Answer 1

Answer:

Breadth = 35 cm

Area = 2800 cm

Step-by-step explanation:

Perimeter = 230cm

Length = 80 cm

P of rectangle =2(L+B)

230 = 2(80+B)

230 = (2×80)+(2×B)

230=160+2B

230 - 160 = 2B

70 = 2B

B=70/2 = 35 cm

Area of a rectangle = L×B

A= 80 × 35

A = 2800 cm
