Kwesi is putting on sunscreen. he uses 3ml to cover 45 cm2 of his skin. he wants to know how many milliliters of sunscreen g he needs to cover 240 cm2 of his skin. he assumes the relationship between milliliters of sunscreen and area is proportional.

The answer is

Step-by-step explanation:

we know that

He uses to cover of his skin

so

by proportion

Find how many milliliters of sunscreen are needed to cover  

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
