A rectangular garden has a walkway surrounding it that is 4 feet wide (a uniform width of 4 feet). The garden's dimensions are 15ft x 20ft. Explain or show how to find the area
of just the walkway and include your answer in ft". HINT: Draw a picturell I

300 square feet  

Step-by-step explanation:

length of walkway = 20 + 2x

width of walkway = 15 + 2x

A(x) = (20 + 2x)(15 + 2x)

A(x) = 300 + 30x + 40x + 4x2

A(x) = 300 + 70x + 4x2

last option: rhombus or kite

step-by-step explanation:

a kite and rhombus have the same shape. as we don't have any specific formula for the calculation of area of kite. the diagonals are used to calculate the area of a kite or rhombus.

the formula for area of rhombus is given by:

here, d_1 is the first diagonal and d_2 is the second diagonal.

so,

last option is the correct answer ..

answer: 15
