The answer is <span>length = 10 yd, width = 2 yd
proof
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w,
and Area = 20 =l x w = (5x2) x 2 =20</span>
Yes it is if the word problem applies to or is about math
Answer:
length=76 width=34
Step-by-step explanation:
to get the length on one side the equation is 2w+8 and the width is w so times them both by two to solve for all sides it is:
2w+8+2w+8+w+w which simplifies to 6w+16
if the perimeter is 220 it is 6w+16=220
you then minus 16 from both sides and get: 6w=204
next you divide both sides by 6 to get w= 34
if w=34 on one side and the length is 2w+8 you substitute the w for 34
2(34)+8 which equals 76
Answer:
Step-by-step explanation:
πr² = 18
v = 90 cm³
1/3πr² h = 90
1/3*18*h = 90
h = 90*3/18
h = 5*3 =15 cm
