The answer is 25m.
Height = 15
Length = 25
Height+lengthx2= 80(perimeter)
Height x length=375m2(area)
Answer=10:40
Explanation:
Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50
So 1:4
Add it up
1+4=5
So 5 total units
$50=5
Divided by 5
$10=1 units
So 1:4=10:10 times 4=10:40
