Question

Figure AFigure B

Answer 1

Using the given information, the area of figure B is 315 ft²

Calculating Area

From the question, we are to calculate the area of figure B

In the given diagram, figure B is made up of a triangle and a square

∴ Area of figure B = Area of triangle + Area of square

Area of triangle = $\frac{1}{2} bh$

Where b is the base

and h is the height

Area of square = $l^{2}$

Where $l$ is the length of a side

In the diagram,

$l = b = 15 \ ft$

$h =12 \ ft$

∴ Area of figure B = $(\frac{1}{2}\times 15 \times 12) + 15^{2}$

∴ Area of figure B = (15×6) + 225

∴ Area of figure B = 90 + 225

∴ Area of figure B = 315 ft²

Hence, the area of figure B is 315 ft²
