Answer:
nnnnnnnnnnnnoooo clueeeeeeeeee
Step-by-step explanation:
Step-by-step explanation:
if you have the answer, why do you ask ?
anyway,
l = length
b = breadth
perimeter = 2×l + 2×b = 30 cm
l = b + 10
now we use this identity in the perimeter equation :
2×(b+10) + 2b = 30
2b + 20 + 2b = 30
4b = 10
b = 2.5 cm
l = b + 10 = 2.5 + 10 = 12.5 cm
Answer:
There are two solutions. (-2,6) and (0,0).

Answer:
104.5 meters square
Step-by-step explanation:
The area of a trapezoid is found using the formula A = 1/2 (a + b)h. Substitute a = 8, b = 11 and h = 12.
The area is A = 1/2(8+11)*12.
A = 1/2 (19)*12 = 104.5
