Question

Part 1 and there is one more part and after this there is no moreeeee!

Answer 1

So you have a 10x10, a 7x10, and a 5x3 rectangles. You also have 2 3x3 triangles. Surface area is equal to the area of all figures combined. For the mall, it is just 1 of the triangles. For the park, it is the 5x3 rectangle and 3x3 triangle.

Answer 2

In this question, we're trying to find the area of the mall and park section.

Mall section:

We can see that the mall is shaped as a right triangle.

To find the area, we would use this equation:

A = h · b/2

The height and base would be 3, so plug in and solve:

A = 3 · 3/2

A= 9/2

A = 4.5

Answer:

The area of the mall section is 4.5 blocks²

Park section:

The park section is shaped differently, but lets cut it into different pieces.

We can make a rectangle with the length of 5 and the width of 3.

We would also have a triangle with the length and height of 3.

Solve the areas for those two and solve.

A = 3 · 3/2

A= 9/2

A = 4.5

A = 5 · 3

A = 15

15 + 4.5 = 19.5

Answer:

The area of the park section is 19.5 blocks²
