Here,
let width(b)be x then,
length (l)=9cm+x
area =112 sq cm
now,
area of rectangle=l*b
or, 112=(9+x)x
or, 112=9x+x^2
or, 0=x^2+9x-112
or, 0=x^2+(16-7)x-112
or, 0=x^2+16x-7x-112
or, 0=x(x+16)-7(x+16)
or, 0=(x-7)(x+16)
either,
0=x-7
or,7=x
x=7cm
Or,
0=x+16
or, -16=x
x= -16[impossible,as distance is never negative] so,
x=7cm
therefore,length = 7cm + 9 cm = 16cm and width = 7cm.

If A represents an angle, its complement is 90-A.
If m<1 = 36, then its complement is 90-36 (degrees), or 54 (degrees).
Answer:
here, Area of s circle is given by;
A=πr²
but, A=1256.00 sq feet and π=22/7
thus, r=√(A/π)
⇒r=√(1256.00/3.142857143)
thus, r=399.64feet
Step-by-step explanation:
im not sure about the first one but im 100% about 2 and 3
2-A
3-D
Answer:
218 cm²
Step-by-step explanation:
= high × wide
= 9 × 2
= 18
= 6 × (5+3)
= 6 × 8
= 48
= 8 × (11+5+3)
= 8 × 19
= 152
area throughout
= 152 + 48 + 18
= 218 cm²
