Unit 1 lesson 10 base and heights of triangle

Formula to find the area of a triangle = × base × height

For triangles A, B and D, the base occupies 4 squares and the height occupies 4 squares.

Therefore, area = × 4 × 4

                          = 2 × 4 = 8 sq. units

For triangle E, base occupies 2 squares and height occupies 8 squares.

Therefore, area = × 2 × 8

                          = 8 sq. units

For triangle C, base occupies 3 squares and height occupies 5 squares.

Therefore, area = × 3 × 5

                          = 7.5 sq. units

Hence, triangles whose area is 8 sq. units are A, B, D and E.

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
