Answer:
Beth area=16 in²
Adam width=4 in
Step-by-step explanation:
Considering the attached image, Beth's area will be 4*4=16in²
Since Adams area is 12 more then his area will be 12+16=28 in²
Since area is given as A=lw where l is length and w is width then
28=7w
w=28/7=4 in

Answer:
x = 26.2 cm
Step-by-step explanation:
To find the value of x, we will use cosine rule;
x² = 15² + 18² - 2(15 × 18)cos105
x² = 225 + 324 - 540(-0.2558)
x² = 549 + 138.132
x² = 687.132
x ≈ 26.2 cm
