The base of a triangle images 5.5 feet its height is 3 feet in 4 pounds of mulch are needed to cover a square foot how many pounds of much will be needed to cover the garden

The area of the triangle must be determined. then multiply the area of the triangle by 4lb/1ft2
the equation for the area of a triangle is A = b times h/2
the base equals 5.5 feet and the height is 3 feet.
A = (5.5fttimes 3ft) /2=8.25ft2
4lb mulch is needed for each square feet

8.25ft2 times 4lbmulch/1ft2 = 33lb mulch

2.4+3.2t. you get the answer by adding the ones with variables and ones without
