Answer:
60.69cm^2
Step-by-step explanation:
5.1^2 = 26.01
5.1/2 = 2.55
2.55 × 5.95 = 15.1725
15.1725×4 = 60.69
60.69 + 26.01 = 60.69cm^2 nice

Answer:
To convert mixed number 10 3/17 to improper fraction, you follow these steps:
First, note that 10 3/17 is a mixed number, also know as mixed fraction. It has a whole number and a proper fraction. The numbers in the mixed fraction are defined as follow:
10 = whole number
3 = numerator
17 = denominator
Multiply the whole number by the denominator
10 × 17 = 170
Add the product from Step 1 to the numerator
170 + 3 = 173
Write answer from Step 2 over the denominator
173/17
The mixed number 10 3/17 converted to improper fraction is therefore :
173/17

Answer:
Step-by-step explanation:
hello :
let y the length and x the width
A the area and P the perimeter
so : A= xy and P = 2(x+y) ....y > x and x >0 ; y>0
xy = 1764 ...(1)
y = x +13....(2) put this value in (1) : x (x+13) = 1764
x²+13x -1764 = 0 ...quadratic equation
calculate : Δ = b² -4ac a =1 and b =13 and
c = -1764
Δ = (13)² - 4(1)(-1764) = 169 +7056 = 7225=85²
X1 =(-b-√Δ)/2a =(-13-85)/2 < 0 refused (x >0)
X2 =(-b+√Δ)/2a =(-13+85)/2 = 72/2 = 36
so : x= 36 put this value in (2) : y = 36+13 = 49
the perimeter is : P = 2(x+y)
P = 2(36+49) = 170 m
