Answer:
Let's solve for the rectangle above, using the formula;
A = L*W
Replace those values:-
A = L*W
A = 3(15)
A = 45, is the area of the above rectangle.
Now for the middle rectangle, using the formula;
A = L*W
Replace those values:-
A = L*W
A = 8(9)
A = 72, is the area of the middle rectangle.
Now to solve for the circle below we know it's 1/4 of a regular circle, so using our formula and using 3.14 for pi;
A = π[tex]r^{2}[/tex] x 1/4
Replace those values:-
A = 3.14(6^2) x 1/4
A = 3.14(36) x 1/4
A = 113.04 x 1/4
A = 113.04/4
A = 28.26, is the area of the quartered square.
Now we add all the areas together;
45 + 72 + 28.26
= 145.26 square centimetres, is your area of the whole entire figure.
