I can help you set up the equation, if you don't actually practice isolating you're never gonna learn,
it says the /sum of a number and seven/ which means n+7
is equal to /five less than the number/ so n-5
so your two parts are
n+7 = n-5

Answer:

Area of the garden = 98 + 19.25 = 117.25 ft²

Step-by-step explanation:

Area of the garden = area of the rectangle + area of the semi-circle

Area of the rectangle = L x B = 14 x 7 = 98 ft²

Area of the semi-circle = 1/2 x πR² = 1/2 x 22/7 x 3.5² = 19.25 ft²

Hence area of the garden = 98 + 19.25 = 117.25 ft²
