Question

the length of a rectangular plot is 1.5 times its breadth. 20% of its perimeter is 20 meter. find the area​

Answer 1

Resposta:

600m²

Explicação passo-a-passo:

Length  = 1.5 B

Perimeter = 2 ( L + B)    -->    2 (1.5B + B)   -->  5B

20% of 5B = 2

20/100 * 5B = 20   -->  B = 20m

L = 1.5 * 20 = 30m

Area = L * B = 30 x 20 = 600m²
