Question

A rectangular plot of grass 25m by 22m has a gravel walk 1.5 m wide all round it on the outside .find the area of the gravel walk

Answer 1

Answer:

$132 {m}^{2}$

Step-by-step explanation:

$the \: area \: of \: plot \: = (side \times side) {unit \ }^{2} \\ = (25 \times 22) {m }^{2} = 550 {m}^{2} \\ without \: \: the \: gravel \: walk \\ area = (25 - 3 \times 22 - 3) {m}^{2} = (19 \times 22) = 418 {m}^{2} \\ so \\ the \: area \: of \: gravel \: walk \: = (550 - 418) = 132 {m}^{2}$
