Find the area of the composite shape

hope that help mark me brill

Step-by-step explanation:

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together.

Step-by-step explanation:

Radius = 4 ft

Side of the square = 8 ft

Area of circle = πr² ≈ 3 × 4² = 48 ft²

Square area = a² = 8² = 64 ft²

area of composite shape = Square area - Area if circle = 64 - 48 = 16 ft²

step-by-step explanation:

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
