Answer:

Draw it with 9 cm for length and width.

Step-by-step explanation:

The product is the maximum area when the length and width are as close as possible, or equal to each other. Because length and width are 2 sides each, we can divide 36 by 4, which is 9.

9x9 = 81 cm^2. This is the largest area possible.

Find the perimeter RST. Round answer to the nearest tenth<br> Show all the work
kow [346]

Answer:

35.1 units

Step-by-step explanation:

Imagine a right-angled triangle with RS as hypotenuse. The base would be 3 units and the height would be 6 units. By Pythagorus:

RS²=3²+6²

RS=\sqrt{45}≈6.7 units

Imagine a right-angled triangle with RT as hypotenuse. The base would be 9 units and the height would be 12 units. By Pythagorus:

RT²=9²+12²

RT=\sqrt{225} = 15 units

Imagine a right-angled triangle with TS as hypotenuse. The base would be 12 units and the height would be 6 units. By Pythagorus:

TS²=12²+6²

TS=\sqrt{180}≈13.4 units

Perimeter=RS+RT+TS

=6.7+15+13.4

=35.1 units

liraira [26]

Answer:

No she doesn't have enough paint.

Step-by-step explanation:

You have to find the area of both walls then subtract both areas by 250. It would give you a negative number, meaning there is not enough paint.
