Step-by-step explanation:
The element at row i column j in the product is the dot-product of row i of the first matrix and column j of the second matrix. For example, row 2 column 1 of the product is ...
(row 2) · (column 1)
[3, -2, 4] · [2, 7, 1] = (3)(2) +(-2)(7) +(4)(1) = 6 -14 +4 = -4
The attachment shows the complete product matrix. It is convenient to let a spreadsheet or graphing calculator do the tedious repetitive arithmetic.
Answer:
a)91 m
b) 58 m
Step-by-step explanation:
a) length × width = area →
length × 61 = 5551
length = 5551/61 = 91
b) perimeter = 2×( length + width)
292 = 2×( 88 + width) = 176 + 2×width
292 - 176 = 2× width
116 = 2× width → width = 116/2 = 58 m
