Chapter 3: Q. 393 (page 407)

A triangular road sign has base $30$ inches and height $40$ inches. What is its area?

Short Answer

Expert verified

The area of the triangular road sign is $600$ square inches.

Step by step solution

Step 1. Given Information

The base of the triangular road is $30$ inches and the height is $40$ inches.

We have to find its area.

Step 2. Translate into an equation

Let Abe the area.

The formula of the area of the triangle is $A = \frac{1}{2} \times b \times h$

So, the equation is $A = \frac{1}{2} \times 30 \times 40 .$

Step 3. Solve the equation

By proceeding with the equation we get,

$A = \frac{1}{2} \times 30 \times 40 A = 600$

Thus, the area of the triangular road is $600$ square inches.

Step 4. Check the answer

To check the answer use the area of the triangular road

Thus,

$600 = \frac{1}{2} \times 30 \times 40 600 = 600$

It is true.
