Question 1019828
Hi there,
Make the second side = 'x'
First side = 2x - 10
Third side = 2x - 19
Perimeter = 61m
x + (2x - 10)+ (2x - 19) = 61
x + 2x - 10 + 2x - 19 = 61
Collect like terms
x + 2x + 2x = 61 + 10 + 19
5x = 90
x = 18m
First side = 26m
Second side = 18m
Third side = 17m
Hope this helps :-)
