Question

Please Help Giving Brainlist!!!!! Given that the area of rectangle IJKL is 490 units^2, what are its length and width?

Answer 1

Answer:

Option 4

Step-by-step explanation:

Equating given length and width to the area :

• 8x(5x) = 490
• 40x² = 490
• x² = 490/40
• x² = 12.25
• x = 3.5

Finding the dimensions :

• length = 8x = 8(3.5) = 28 units
• width = 5x = 5(3.5) = 17.5 units

Answer 2

• LB=490
• 8x×5x=490
• 40x²=490
• 4x²=49
• (2x)²=7²
• 2x=7
• x=7/2
• x=3.5

• L=8(3.5)=28units
• B=5(3.5)=17.5units
