Question

Please help me I need this done I need someone who will SHOW WORK and complete all the questions for 15 points please help me if you can!

Answer 1

see below

Explanation:

1a) Area of rectangle = L * W

A = 57*35 = 1995 in²

1b) A =L * W = 8 * 14.3 = 114.4 cm²

1c) Area of Δ =1/2 base x height

Height is always perpendicular to the base!!!

base = 36; height = 15

A of Δ = (1/2) * 36 * 15 =18*15 = 270 m²

1d) Area of Δ =1/2 base x height

base = 27.3; height = 16.8

A of Δ = (1/2) * 27.3 * 16.8 = 229.32 rounded to final answer 229.3 in² !!!!

1e) Area of Δ =1/2 base x height

base = 14; height = 9

A of Δ = (1/2) * 14 * 9 = 7 * 9 = 63 yd²

1e) Area of Δ =1/2 base x height

base =30 ; height = 40

In this case base also can be 40 and height 30 b/c it's right Δ

A of Δ = (1/2) * 30 * 40 = 15 * 40 =600 ft²

Answer 2

1.1995

2.114.4

3.270

Explanation:

1. Multiply the length and width

2. Multiply 14.3*8

3. Multiply 15*36 and divide the product by 2

to find the area of a rectangle, multiplty length times width

for the area of a triangle, multiply the bottom of the triangle by the height and divide it by 2.
