Find the area of the shape

54 unit^2.

Step-by-step explanation:

The area = the sum of the 2 triangles.

Area of a triangle = 1/2 * base * height.

So here:

A = 1/2 * 4 * 12 + 1/2 * 5 * 12

= 24 + 30

= 54

Explanation:

the area of the polygon = the area of the triangle ADC + the area of the triangle ABC

the area of a triangle = (height × base)/2

A ADC = (DE×AC)/2

A ADC = (4×12)/2

A ADC = 48/2

A ADC = 24 u²

A ABC = (BF×AC)/2

A ABC = (5×12)/2

A ABC = 60/2

A ABC = 30 u²

ABCD = A ADC + A ABC

ABCD = 24 + 30

ABCD = 54 u²
