Hi there!

\large\boxed{ 9.4m}

Find the perimeter using the formula:

P = 2l + 2w

It is given that the dimensions are 2.8 × 1.9 so plug these number into the equation:

P = 2(2.8) + 2(1.9)

P = 5.6 + 3.8

P = 9.4m

1.what is the value of x? ( 1st pic)
balandron [24]
For the first picture using Pythagorean Theorem, we know that a^2 + b ^2 = c^2 but since we only know c ( 99.2) and b ( 62 ) we need to use the theorem to find a the equation we use for that is : 
A = square root of ( c^2 - B^2 ) 
A = 77.44

ArbitrLikvidat [17]

<u>Answer:</u>

• Equation = 2(\frac{7}{4}w  + w) = 176

• length = 56 ft

• width = 32 ft

<u>Step-by-step explanation:</u>

The ratio of the length to width is 7:4.

∴ \frac{l}{w} = \frac{7}{4}

⇒ l = \frac{7}{4} w                 [Equation 1]

We know that the perimeter of the garden is 176 feet.

∴ 2(l + w) = 176

⇒ 2(\frac{7}{4}w  + w) = 176

⇒ \frac{7}{4} w + w = 88        [From Equation 1]

⇒ \frac{7 w + 4w}{4}  = 88

⇒ \frac{11w}{4} = 88

⇒ 11w = 352

⇒ w = \bf 32 \space\ ft

We know from Equation 1 that:

l = \frac{7}{4} w

∴ l = \frac{7}{4} (32)

⇒ l = \bf 56 \space\ ft
