Answer:
Breadth=45 cm and Area = 3150
Step-by-step explanation:
Length= 70 cm and breadth =?
Perimeter=2(l+b)
or,230=2(70+b)
or,230=140+2b
or,230-140=2b
or,90/2=b
or,b=45cm
Breadth=45cm and Length=70cm
Area=l×b
=70×45
=3150cm^2
Answer:
No, because 3(2)+3 not equal to 15
Step-by-step explanation:
let the goals of Skylar be x
goals of wyatt be y
y=2x
x+y=15
3x=15
x=5
y=10
If 1 inch = 2.5 yards then
x inch = 80 yards
cross multiplying we have:
80 × 1 = x × 2.5
x = 80÷ 2.5 = 32 inches
therefore the picnic area is 32 inches in the drawing.
