Question

Help me please I don’t know what to do

Answer 1

179.3 square units

Explanation:

We have to find the area of the rectangle and area of semicircle using the formula and then add the areas.

Area of rectangle:

length = 14 units

width = 10 units

`\sf \boxed{\text{\bf Area of rectangle = length * width}}`

= 14 * 10

= 140 square units

Area of semicircle:

diameter of semicircle = width of the rectangle

d = 10 units

r = d ÷ 2

= 10 ÷ 2

= 5 units

`\boxed{\text{\bf Area of semicircle = $(1)/(2)\pi r^2$}}`

`\sf = (1)/(2)*3.14*5*5\\\\ = 39.26\\\\ = 39.3 \ square \ units`

Area of the figure = area of rectangle + area of semicircle

= 140 + 39.3

= 179.3 square units
