$\approx \$27.10$

Work Step by Step

First we find the total wood length with consistent units: $85~cm*\frac{1~m}{100~cm}=0.85~m$ $1.3*2+0.85*2=4.3~m$ Next we multiply by the per-meter price: $4.3~m*\frac{\$5.89}{1~m}\approx\$25.33$ Next, we include the sales tax of 7%: $\$25.33*1.07=\$27.103\approx \$27.10$
