Question

the Anderson are going on a long sailing trip during the summer however one of the sails on their sailboat ripped and they have to replace it the sail is pictured below if the sailboat sails are sale for 2$ per square foot how much will the new sail cost?

Answer 1

Firs we need to calculate the area of a triangle

`A=(b\cdot h)/(2)`

b= base

h=heigth

in our case

b=8ft

h=12ft

`A=(8\cdot12)/(2)=(96)/(2)=48ft^2`

then we will calculate the total cost

1 square foot ----- $2

48 square feet ----- x

the total cost is 48*2=96

total cost is $96
