Pleasa ! finding area

the area of the living room is:

9 m²
15 m²
20 m²
25 m²

the area of the kitchen is:

8 m²
12 m²
16 m²
20 m²

the area of the dining room is:

2 m²
6 m²
8 m²
16 m²

All these rooms are rectangles so to find the area of the rooms multiply length by width.

Living Room: 5x4 = 20 m²

Kitchen: 4x3 = 12 m²

Dining Room: 4x2 = 8 m²

step-by-step explanation: i dont

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
