Answer and explanation:
1.Given a rectangle with length l and width w, the formula for the area is: A = lw (rectangle)
2.The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
3.The area of a circle is pi times the radius squared (A = π r²).
4.multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.
5.A=1(b1+b2)h
