Answer:
Area = 230 cm
Step-by-step explanation:
We can split this shape into different parts: a rectangle and a triangle (I attached an image below as a visual aid).
The area of a rectangle is given as:
and the area of a triangle is given as:
Let's first solve for the area of the rectangle. The width of the rectangle is 20cm, and the height of the rectangle is 7cm. So, the area is 7 × 20 = 140cm.
Now, let's solve for the area of the triangle. The base of the triangle is 20 cm, and the height of the rectangle is 16 - 7 = 9cm. So, the area is = 90cm.
We add the two values together to get the combined area of the shape. 140 + 90 = 230 cm.
Answer:
a. The width of the rectangular prism is 13 units less than the length.
Step-by-step explanation:
From the information given we know that
a = length of rectangular prism and
= width of rectangular prism
An expression like means that we need to subtract 13 units from the length to obtain the width of the rectangular prism.
Therefore,
The width of the rectangular prism is 13 units less than the length.
