Exercise 1 Page 586

Use the formula for area of a triangle.

68cm^2

Practice makes perfect

Here we will use the formula for calculating the area of a triangle. A=1/2bh

Let's consider the given figure.

triangles

Now we substitute the value of the base, b= 17, and the value of the height, h= 8, into the formula to calculate A.

A=1/2bh

b= 17, h= 8

A=1/2( 17)( 8)

a/c* b = a* b/c

A=8/2* 17

Calculate quotient

A=4*17

Multiply

A=68

The area of the triangle is 68cm^2.
