Answer:
Step-by-step explanation:
Second equation times 3:
1st equation minus equation above:
Insert to equation:
Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
24cm
You multiply 6*4=24. Hope this helps! Also can u mark brainliest i need one more :)
