The volume is 70/9 or 7 7/9.
=========================================
$\frac{5}{3} \times \frac{7}{3} \times \frac{2}{1} = \frac{70}{9}$
$\frac{70}{9} = 7 \frac{7}{9}$
$l \times w \times h = v$

FinnZ [79.3K]

Answer:

The length of the hypotenuse ≈ 39.7 cm

Explanation:

Since the given triangle is a right-angled triangle, this means that we can apply the Pythagorean theorem.

The equation for Pythagorean calculation is:

(hypotenuse)² = (first leg)² + (second leg)²

In the given, we have:

first leg = 30 cm

second leg = 26 cm

Substitute with the givens in the above equation to get the hypotenuse as follows:

(hypotenuse)² = (30)² + (26)²

(hypotenuse)² = 1576

This means that:

either hypotenuse = √1576 = 39.69 ≈ 39.7 cm ..........> accepted

or hypotenuse = -√1576 = -39.69 ......> rejected as length can't be negative

Hope this helps :)

A rectangular vegetable patch has an area of 56 square meters and a

vredina [299]

Answer:

The dimensions of the vegetable patch is 8 m by 7 m.

Step-by-step explanation:

Area of a vegetable patch is 56 square meters and the perimeter is 30 m.

If l is length and b is breadth, then area and perimeter of a rectangle is given by :

$A=l\times b$

$P=2(l+b)$

Substituting the values in the above formulas as :

$l\times b=56\ ....(1)$

and

$2(l+b)=30\\\\l+b=15\ .....(2)$

We need to solve equation (1) and (2) to find the values of l and b such that :

Equation (2), l = 15 - b

Equation (1) becomes,

$(15-b)b=56\\\\b=7\ m, 8\ m$

If b = 7 m, so, l = 8 m

If b = 8 m, l = 7 m

So, the dimensions of the vegetable patch is 8 m by 7 m.
