Answer:

2.38

Step by step explanation :

i assume you need help with question 2 b as your first question is correct

Question 2b)

First calculate the area of the rectangle :

which is length * width

2.8 * 1.4 = 3.92

area of rectangle = 3.92

Second calculate the Area of the circle inside:

notice that the circles radius is not just 0.7 but the base has a length of (2.8/2 = 1.4)

therefore find the area of the circle using 1.4

use πr^2 / 2

because its half a circle

π * 1.4*0.7 /2 = 1.5393804

area of circle = 1.5393804

now subtract the area of the circle from the area of the rectangle .

3.92 -1.5393804 = 2.3806196
