Question

Find the area of a rectangle whose width is 15 centimeters and whose length is 3 centimeters more than twice its width

Answer 1

So the formula for triangle area is

A = 1/2(l*w)

With the data you gave me, we just need to plug it in.

A = 1/2( (2+[15*2])*15)

A = 1/2( (2+[30])*15)

A = 1/2( 32*15)

A = 1/2( 480 )

A = 240
