Answer 1

66x

Explanation:

Rect = bh

Rect = 15 x 4x

Rect = 60x

Triangle = (bh) / 2

B = 7x - 4x

B = 3x

A = 15 - 11

A = 4

Tri = (4 x 3x) / 2

Tri = 12x / 2

Tri = 6x

All = Rect + Tri

All = 6x + 60x

All = 66x

(I promise it's right this time)

Answer 2

66x

Explanation:

Separate the shape into a rectangle and a triangle.

Dimension of the rectangle:

• length = 15
• width = 4x

Dimension of the triangle:

• base = (15 - 11) = 4
• height = (7x - 4x) = 3x

Area of a rectangle = length × width

Area of a triangle = 1/2 × base × width

Total area = area of rectangle + area of triangle

= (15 × 4x) + (1/2 × 4 × 3x)

= 60x + 6x

= 66x
