Question

find the perimter and area of the following figures​

Answer 1

area of rectangle=l×b

=10×7

=70m^2

perimeter of rectangle=2(l+b)

2(10+7)

2(17)

2×17

=34

please follow me and mark my answer as brainliest

Answer 2

$area \: is \: = \: l \times b = 10 \times 7 = 70 {m}^{2}$

$perimeter \: is \: = \: 2(l + b) = 2(7 + 10) = 2(17) = 34m$

$area \: of \: semicircle \: is \: = \frac{\pi {r}^{2} }{2} = \frac{22 \times 3.5\times 3.5}{7 \times 2} = 11 \times 0.5 \times 3.5 = 19.25{cm}^{2}$

$perimeter \: of \: semicircle \: is \: = \pi r + d = \frac{22}{7} \times 3.5 + 7 = 22 \times 0.5 + 7 = 11 + 7 = 18cm$
