Question

which formula should be used to find the area of the composite shape? A = 4(1/2Xbh) lw B. A=4bh+lw C. a=4bh+lw d. 2bh+bh The composite shape is a four pointed star.

Answer 1

D. 2bh+bh

Explanation:

You can divide that shape into five separate pieces, 4 triangles and 1 square.

The formula for the area of a triangle is A=1/2bh.

Multiply this by 4 becuase there are 4 triangles and you get A=2bh.

Then you add on the area of the square and you have A=2bh+bh
