Question

please give me answer in this question number 16

Answer 1

Hey there,
Down here ⏬

☆ First of all, we need to find the area of Rectangle = l×b
= 5×12 = 60 m^2

☆ We wanna find out the length of BD in order to find out ,Diameter, in turn, Raduis.

By pythagorean theorom ,
hyp^2 = alt^2 + base^2
= (BC)^2 = (12)^2 + (5)^2
(BC)^2 = 144+25
(BC)^2 = 189
BC = 13 is the diameter. Radius = 13/2 = 6.5

☆ Area of circle = 2×22/7×(6.5)^2
= 265.57 m^2

☆ Area if shaded region = Area of circle - Area of Rectangle
= 265.57-60
= 72.665 m^2

Hope it helps
