Answer: 7 inches
Step-by-step explanation: look at the base that is 7inches
By seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.
We are given that a recipe for two people requires 1kg of rice to 150 g of meat.
That is the proportion of rice to meat is:
1 kg : 150 g
1000 g : 150 g
100 : 15
20 : 3
Now, we are also given that 1 kg that is 1000 g of dish is to be prepared.
Let the portion of rice in it be x.
Portion of meat = 1000 - x
ATQ:
20 : 3 :: x : 1000 - x
20 / 3 = x / (1000 - x)
20,000 - 20 x = 3x
23 x = 20,000
x = 20000 / 23 = 870 ( approx.)
1000 - x = 1000 - 870 = 130.
Therefore, by seeing the proportion, we get that approximately, 870 g of rice is required and 130 g of meat is required for the recipe.

Define x :
--------------------------------------------
Let the shorter leg = x
Longer leg = x + 7
Hypotenuse = x + 7 + 7 = x + 14
--------------------------------------------
Solve x :
--------------------------------------------
a² + b² = c²
x² + (x+7)² = (x+14)²
x² + x² + 14x + 49 = x² + 28x + 196
2x² + 14x + 49 = x² + 28x + 196
x² - 14x - 147 = 0
<span>(x - 21)(x + 7) = 0
</span>x = 21 or x = - 7 (rejected, because length cannot be negative)
--------------------------------------------
Find the legs and hypotenuse:
--------------------------------------------
shorter leg = x = 21
longer leg = x + 7 = 21 + 7 = 28
hypotenuse = x + 14 = 21 + 14 = 35
