1. 80 sheep when increase in the ratio 5:4 becomes 100 sheep.
2. The perimeter of the shape is : 26cm
<h3>What is Perimeter?</h3>
Perimeter is the outside boundary of a shape.
It is usually calculated by summing up all the length of the sides of that shape.
Analysis:
1. if the sheep is increased in the ratio 5:4
then new number of sheep becomes 5/4 x 80 = 400/4 = 100 sheep
2. The perimeter of the shape is the sum of all the sides of the shape = 7 + 4 + 10 +5 = 26cm
