Step-by-step explanation:
Let's call x the lenght and y the height. The perimeter will be:
p = 2x + 2y = 10
When the lenght is halved and the height double we'll have:
p = x + 4y = 14
These 2 equations form a system of equations2 that can be solved and give as result:
y = 3
x = 2
88 * 2 = 176 ;
88 * 3 = 264 ;
88 * 4 = 362 ;
...................
116 degrees. It’s simple.
56 is what the low was, but the high was 60 more.
Therefore,
56+60=116
