Question

the length and breadth of a playground is 30mand 12m respectively find its perimeter and area​

Answer 1

Answer:

Perimeter = ${84\:m}$

Area= ${360\:m}^{2}$

Step-by-step explanation:

Perimeter -

$\color{black}\boxed{\colorbox{saffron}{Perimeter-2(length+breadth) }}$

$2(30 + 12) \\ \\ = 2 \times 42 \\ \\ = 84 \: m$

ㅤ

Area-

$\color{black}\boxed{\colorbox{saffron}{Area - length×breadth}}$

$30 \times 12 \\ \\ = 360 \: {m}^{2}$
