Answer:
10*15= 150
150 *8= 1,200
1,200 ÷ 2 = 600.
Step-by-step explanation:
Answer:
I believe 21 cm
Step-by-step explanation:
So we can call the width of the rectangle x.
So then the length would be 4x.
The perimeter would then be 10x.
Since the perimeter is 70, we can say 70 = 10x.
And then simplify that to 7 = x.
So the length of a rectangle would be 28 cm, and the width would be 7.
So to find the area, just multiply length by width.
28*7 = 196 square cm
So the rectangle's area is 196 square cm.
I hope I helped!
The temperature would be -10 degrees
