Answer:
(a) = 71 cm
(b) = 89 cm
Step-by-step explanation:
(a.)
perimeter of a rectangular field = 324 m
length (l) = 91 m
width (w) = ?
Now,
<em>Perimeter Of Rectangle </em>
<u>= <em>P = 2(l + w)</em></u>
= 2(91 + w) = 324m
= 182 + 2w = 324m
= 2w = 324 - 182m
= 2w = 142m
= w = 142/2
= w = 71
(b.)
area of rectangular painting = 5696 cm²
width (w) = 64 cm
length (l) = ?
Now,
<em>Area Of Rectangle </em>
A = <em><u>l × </u></em><em><u>w</u></em>
= l × 64 = 5696
= l = 5696/64
= l = 89 cm
<h2>
<em><u>VERIFICATION</u></em><em><u>:</u></em><em><u>-</u></em></h2>
FOR (a)
= P = 2(l + w)
<em><u>= P = 2(91 + 71) = 324 cm</u></em>
FOR (b)
= l × w
A = 89 × 64 = 5696
Answer:
9 times 800/9 equals 800. (Answer is 800/9)
Step-by-step explanation:
<u>Key skills needed: Equation, Division, Fractions</u>
1) Let's say the number is the variable "x".
2) So this means 9 times x = 800
9x = 800
3) Divide both sides by 9 and you will get x equal to 800/9. If you want this in mixed number form, it is --> 88 8/9
