Answer:
56
Step-by-step explanation:
Because when you want to find the erea of something you mutiply the width and length
length=long
with=wide
7 meters long, length × 8 meters wide,with
length×with
7×8=
=56
também n sei. Se alguém souber por favor ajuda aí plissss
The answer is 257.08m. Explanation: you know that one side of the square in the middle is 50m. This is the same as the diameter of one of the half circles on each side. The perimeter of a circle is the formula C=2(pi)r, where r is the radius. Dividing 50 by two will get you the size of the radius, then just plug it into the equation to find the perimeter of both rounded sides (a full circle). The two circular sides equal 157.08m, so then you just need to add the flat sides, which are both 50m since they’re congruent. 157.08m + 50m + 50m = 257.08m, so the perimeter of the shape is 257.08m.
