Ben plans some turf to cover his triangular lawn which is 4.8 yards high. Its area measures 40.2 square yards. How much does the base of the lawn measure?
16.75 square yards because area of a triangle is half the base times the height. 40.2÷4.8 is 8.375. Since that is half the base, multiply by two. 8.375×2 is 16.75. Hope that helps! :D
