Mrs. harris purchased a large pack of erasers for her math class. she sets aside 10 erasers to keep
at her desk and then shared the remaining erasers equally among 15 math students. if each student
receives 4 erasers, write and solve an equation to find the number of erasers 'p' that were in the
original package.

A = area of triangle + area of rectangular + half of the circle area

triangle area = 1/2 × base × height

triangle area = 1/2 × 3 × 5 = 15/2 = 7.50

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

rectangular area = length × width

rectangular area = 6 × 5 = 30

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆

circle half area = 1/2 × pi × radius^2

circle half area = 1/2 × 3.14 × 3^2

circle half area = 1.57 × 9

circle half area = 14.13

A = 7.50 + 30 + 14.13

A = 51.63 m^2
