A rectangle has an area of 161.2m2. One of the sides is 5.2m in length.
Work out the perimeter of the rectangle

ok so the perimeter is all the sides added

Step-by-step explanation:

so you just have to add 161.2 and 5.2.

the answer to that is 166.4

but... thats only 2 sides. now just double that and there u go

72.4 m

Step-by-step explanation:

The area of a triangle is

A = l*w

161.2 = 5.2 *w

Divide each side by 5.2

161.2/5.2 = w

31 =w

Now find the perimeter

P =2 (l+w)

P =2 ( 5.2+31)

P =2( 36.2)

P =72.4

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

2nd one in the first row is correct
