Question

Ummm i don’t understand these I just started can someone help

Answer 1

so for question 2 find the area of the rectangle first:

$15 \times 19 = 285$

then you find the area of the triangles:

$15 \times 13 = 195 \\ 195 \div 2 = 97.5$

$15 \times 11 = 165 \\ 165 \div 2 = 82.5$

Add up all the answers:

$285 + 97.5 + 82.5 = 465$

and for question 3, part A, you just find the area of the 2 boxes and multiply:

$5 \times 5 = 25 \\ 25 \times 2 = 50$

$2 \times 5 = 10 \\ 10 \times 4 = 40$

$40 + 50 = 90$

so the surface area of the box is 90 square inches therefore the paint covered 90 square inches. For part B, just add up the length of the thick black lines:

$5 + 5 + 5 + 5 + 2 + 5 + 5 + 5 + 5 + 5 + 5 + 2 + 5 + 5 = 64$

How these helped have a good day
