Answer:
the answer your looking for is a pyramid
Step-by-step explanation:
The answer is the second option you are correct !
6/7 is in fraction format . . . for it to be in decimal format it would be 0.8571 . . .
Let the dimensions be x and y
Given that the area is 40m²
xy = 40 ----------------- (1)
Given that the perimeter is 26
2(x + y) = 26
x + y = 13
x = 13 - y ---------------- Sub into (1)
(13 - y)y = 40
13y - y² = 40
y² - 13y + 40 = 0
(y - 8)(y - 5) = =
y = 8 or y = 5
The dimensions are 8 meters and 5 meters
