Answer:
its 2.62
Step-by-step explanation:
So, we know the perimeter is 24 cm. and the top part is the left part, (x) + 2, but remember, we need to have it be a number that, multiplied by 2, is 24. So, using this formula, the length, (top / bottom) is 7, and x = 5. Because 5 + 5 = 10, and when length is +2, it adds up to 14. 10 + 14 = 24. So, length is 7, width, (left, right) is 5.
Answer:
factorisation
Step-by-step explanation:
A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b
